Hair follicle drug screening is in fact relatively simple and merely requires a sample of hair in order to be completed. Parents who are worried about their teen's use of drugs can collect a fiber of hair from their pillow. Employers can request a example from their staff. One time a hair sample has been collected, it is preserved in an packet and sent to a participating lab for completion. Hair drug test is best and more accurate than other drug screening forms.

For instance, hair sample drug screen can identify drug use for up to 90 days after use. The detection window is much better in hair follicle drug testing (compare it to few days for urine and saliva based drug screening) because trace amounts of drug chemicals become trapped in each one hair. A easy laboratory test can detect these trace chemicals making for either a positive or negative test result. One time the results are recorded, you are sent notice of the results. Several companies even provide a telephone service where you call in, enter an account digit and take back the results in that way.

Hair sample drug testing can detect all of the foremost types of drugs, including marijuana, opiates, meth, ecstasy, cocaine, PCP. Hair drug screening can detect the trace amounts of illegal substances trapped in the cortex of the hair for up to ninety days after use.

Employee drug screening programs often incorporate hair follicle drug screening into their policy because of the sheer accurateness of these test. Even though hair test is more costly that a urine test kit, for example, they can provide a level of correctness that is nearly 10 times that of other testing methods. Also, hair drug screening does not involve the embarrassing gathering of examples like that of saliva or urine drug tests. In most cases, a few fibers of hair are all that is required to obtain correct results.

Parents can also benefit from hair sample drug tests. Hair drug testing is discrete and private. An individual can be screened without their knowledge, making it so parents can know the truth about their teen's drug use first before making accusations. By using hair drug tests in the home, parents can defend their teens against drug abuse, and help them quit the abuse should sceen results come back positive.
